To (LZZ whom it may concern.-

Be it known that I, WILLIAM HEOKART, a citizen of the United States,residing at Bradner, in the county of l/Vood and State of Ohio, haveinvented certain new and useful Improvements in Shock-Loaders, of whichthe following is a specification.

This invention consists of novel loading apparatus particularly designedfor agricultural purposes to be used. in the field for lift ing shocksof corn, fodder, or the like from the ground and placing the same upon avehicle for facilitating transportation thereof from one point toanother.

The invention is of course adapted for transferring bundles or shocks ofany kind from the ground to a vehicle or similar support, and a specialfeature of the invention is comprised in the provision of novelelevating mechanism and operating means therefor.

The invention also resides in the special form of support carrying thewhole loader apparatus, said support being adapted for attachment to ahay-wagon or the like and mounted upon a single ground-wheel, enablingthe same to be moved from one place to another without difficulty.

Further, the invention resides in the use of a peculiarly-mountedshock-carrying bar, forming a part of the elevating mechanism of theinvention, said shock-carrying bar being so mounted as to permit ofreversibly disposing the shocks-upon the wagon or vehicle upon whichthey are loaded. As the lower or butt end. of the corn-shock is largerthan the upper end, it will be noted that 1neehanism for so disposingthe shocks that they will be evenly loaded upon the vehicle isparticularly advantageous in a practical device of this class.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had. to the followingdescription and accompanying drawings, in which Figure 1. is aperspective view showing the invention as when in actual use, the samebeing connected with a hay-wagon of ordinary construction, theelevating-arms and bar being shown partially raised or elevated. Fig. 2is a perspective view of the invention, the shock-carrying bar beingshown in the position normally assumed thereby preparatory which it israised and lowered.

to loading a shock or bundle. Fig. 3 is a top plan view, dotted linesindicating the position of the horizontal arm and shock-carrying bar asthe latter are being turned to place the bundle or shock upon thevehicle. Fig. 4 is a bottom plan view of the horizontal arm andshock-carrying bar, bringing out more clearly the operating mechanismfor the shock-carrying lingers, the upright being shown in section. Fig.5 is a vertical longitudinal sectional view, partially broken away,showing the mounting of the shockcarrying bar upon the horizontal arm byFig. 6 is a detail view of the shock-engaging fingers and the operatingmechanism therefor, connecting ropes being shown in dotted lines as wellas the pendent standard of the horizontal arm.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views of the drawings by the same referencecharacters.

The vehicle 1 shown in the drawings is a common form of hay-wagon, thehay-rack 2 being supported thereby in the usual manner. Operated from aside of the wagonbody are U-shaped coupling members 3, and said membersare engaged by hooks 4, carried by the supporting-frame of the loadercomprising this invention. The supportingframe of the loader comprises alongitudinal bar 5, a bar 6 projecting at an angle to the bar 5 andextending therefrom at the rear end of the latter, and a vertical post7, rigid with the members 5 and 6 aforesaid, the lat ter being firmlysecured thereto. The post 7 carries the ground-wheel 8, which issuitably mo untcd at the lower end of the post 7. The main operatingmechanism and elevating means orming a part of this invention arecarried by the post 7, and in order that the supporting-frame of theloader may be held upright when detached from the wagon 1 the outer endsof the bars 5 and 6 of said frame are provided with pivoted members 9,adapted. by pivotal movement to be thrown downwardly to form legscooperating with the ground-wheel 8 to support the device in a mannerabove mentioned. The members 9 of the bars 5 and 6 are provided with thehooks 4 before described, and when these members 9 are connected withthe wagon said members are approximately in alined positions with regardto the bars 5 and 6 by which they are carried.

Pivoted to the vertical post 7 or hingedly secured thereto for turningmovement is a vertical upright or mast 10, the pivotal connectionsbetween the upright and the post 7 being indicated at 11. The upright 10supports a horizontal arm 12, which projects outwardly therefrom, saidarm 12 being adapted to be raised and lowered by reason of the manner ofconnecting the same with the said upright 10. The upright 10 is providedupon a side thereof with a vertical guide-plate 13, and spaced guidemembers 14 project rearwardly from the rear or inner extremity of thearm 12, having rollers 15 to engage the guide-plate 13 upon the rearside of the latter, so as to afford a connection between the parts 10and 12, admitting of free vertical movement of the latter. In order thatthe arm 12 may not sag at its outer end and to also facilitate the freevertical movement thereof, a bracket 16 is projected from the under sideof the arm near its inner end, said bracket embodying spaced verticalsides carrying a roller 17, which engages the outer surface of the plate13 to reduce the friction between the arm 12 and the upright 10 as thearm is raised and lowered. Diagonally-arranged braces 18 connect the arm12 with the sides of the bracket 16, and the lower extremities of thebraces 18 are formed with extensions 19, projecting in rear of the plate13 at the vertical edges thereof. The extensions 19 are adapted to abutwith a flange 20 at the lower extremity of the plate 13, so as to limitthe downward movement of the arm 12. The upright 10 has a Windlass-shaft21 mounted in suitable bearings thereon, and this shaft carries the drum22 and is operated by a crank-handle 23. A cable or rope 24 is adaptedto wind around the drum 22, being secured thereto at one end, said cablepassing over a pulley 25 at the upper end of the upright 10 to its pointof connection with the arm 12. The operator of the invention stands uponthe supporting-frame adjacent the shaft 21, so that he may readilyoperate this shaft andwind the connection 24 upon the drum 22 to therebyraise and lower the arm 12.

Any suitable pawl-and-ratchet mechanism may be used to prevent turningof the drum 22 when the load is being carried by the arm 12.

The arm 12 carries the shockcarrying bar 26, the latter being pivoted ata point about intermediate its ends to the outer end portion of the arm,as indicated at 27. Extending from the outer extremity of theshockcarrying bar 26, and preferably at an angle thereto, are spacedteeth or tines 28, which are adapted to strike a shock as the loaderadvances thereto, so as to overturn the same and admit of readyengagement of the shock-engaging fingers 29, carried by the bar 26 there.with. The shock engaging fingers 29 are curved in their length andproject from opposite sides of the bar 26 extending downwardlytherefrom. Said fingers 29 are projected from shafts 30, which aremounted in suitable bearing-brackets 31 at opposite sides of the bar 26,said shafts 30 being arranged longitudinally of the bar. A spring 32 isattached at one end to each shaft 30 and at its opposite end to the bar26, said spring being preferably of the coil type, so as to normallycoact with the respective shafts to force the fingers 29 apart into aposition in which they will be open ready to embrace a shock receivedtherebetween. The fingers 29 extend from the shafts 30 at the outer endsof said shafts, and extending from the inner ends of the shafts arecrank-arms 33, said arms being connected by flexible connections, suchas ropes 34, with a transverse Windlass-shaft 35,mounted upon the innerend of the shockcarrying bar 26. The bar 26 is provided with a dependingstandard 36, projecting down wardly from the under side thereof near theinner end of the bar, and this standard 36 is provided with openings atits lower extremity, through which the connections 34 pass. Theconnections 34 extend. from the points of attachment with the crank-arms33 through a respective opening in the standard 36 and thence upwardlythrough an opening in the bar 26. The shaft 35 has a ratchet-wheel 37mounted upon one end thereof, and a crankhandle 38 extends from a sideof the ratchetwheel. When the crank-handle 38 is turned by the operator,the shaft 35,winding upon the connections 34, will pull the crank-arms33 toward each other and will cause the shockengaging fingers 29 toclose together, the above operation being performed when said engagingfingers are about to embracea shock preparatory to loading the latterupon the vehicle. In order to hold the fingers 29 closed after thelatter have been engaged with the shock, a bell-crank pawl 39 is pivotedto the bar 26 adjacent the wheel 37, and this pawl is adapted to engagethe wheel to hold the latter from backward rotation, the springs 32 ofcourse tending toforce the members 29 apart and place tension upon thetwo connections 34 in a mannerreadily apparent. A spring 40 is connectedat one end with the pawl 39 and at the other end with an arm 40 and'coacts with the pawl 39 to hold the same in engagement with the wheel37, and a hand rope or connection 41 is connected with the pawl, so thatthe operator of'the loader may readily disengage the latter from thewheel 37 to permit separation of the fingers 29 in allowing the shock todrop therethrough.

hen the loader is not in use, the members 9 of the frame-bars 5 and 6are of course lowered by breaking joint with said bars, and therebyformlegs, which cooperating with the ground-wheel 8 will properlysupport the loader. To use the loader, it is only necessary to throw themembers 9 up and connect the hooks 4 thereof with the wagon-body. Thenormal portion of the horizontal arm 12 will of course be at the lowerextremity of the upright 10, said arm being so arranged as to projectlaterally from the wagon or vehicle, as shown most clearly in full linesin Figs. 2 and 3. A shock having been overturned, the loader is sopositioned that the shockengaging fingers 29 will be arranged at opposite sides of the shock, whereupon the operator by turning the shaft 35will draw the crank-arms 33 together and cause the fingers 29 to closeabout and firmly embrace the shock in an obvious manner. The abovehaving been done, the crank-shaft 21 is turned and the connection 24 iswound upon the drum 22, so as to gradually raise the arm 12 until thelatter has reached a position about as shown in full lines in Fig. 1.The arm 12 is now swung laterally, the upright 10 turning in the aboveoperation until said arm assumes a position transversely of and abovethe hay-rack 2, which is carried by the wagon 1.. The operator nowactuates the rope 11,

connected with the pawl 39, engaging the.

ratchet-wheel 37, and said pawl is thereby disengaged from theratchet-wheel, permitting the springs 32 under the normal tensionthereof to force the crank-arms 33 apart and separate the fingers 29,the shock carried thereby being dropped upon the hay-rack in thecustomary way. As premised upon hereinbefore, it is desired in order toload the vehicle evenly that the shocks be disposed thereupon with thebutts reversed, and. the mounting of the shock-carrying bar 26 is suchas to permit the above. For instance, inorder that the shock may bedropped to the wagon with the butt-end reversed itis only necessary thatthe operator swing or turn the shoclecarrying bar 26 upon its pivot 27until the said bar is half-way around, whereupon the connection 41 maybe actuated to drop the shock in the manner before set forth.
